| Abstract: | The toxic effects of four insecticides（Beta-cypermethrin,Xianyuanjing,Malathion,Chongshuian）on growth of Dunaliella salina were studied.The results showed that the growth and reproduction of Dunaliella salina were inhibited by Beta-cypermethrin,Xianyuanjing,Malathion,Chongshuian in different degree,and negative growth was caused over a certain concentrations.Meanwhile,24 h,48 h,72 h,96 h half-effective concentrations EC50 of the four drugs on Dunaliella salina were calculated out using the regression equation. |
